Coolant Level Adjustment

Warning
Do not remove the expansion tank cap or
radiator pressure cap when the engine is
hot. When the engine is hot, the coolant
inside the radiator will be hot and also
under pressure. Contact with this hot,
pressurised coolant will cause scalds and
skin damage.
Allow the engine to cool.

Note:
• If the coolant level is being checked
because the coolant has overheated,
also check the level in the radiator
and top up if necessary.
• In an emergency, distilled water can
be added to the cooling system.
However, the coolant must then be
drained and replenished with H4DX
Hybrid OAT coolant as soon as
possible.

If hard water is used in the cooling system,
it will cause scale accumulation in the
engine and radiator and considerably
reduce the efficiency of the cooling system.
Reduced cooling system efficiency may
cause the engine to overheat and suffer
severe damage.
Refit the final drive belt cover as follows:
Align the cover to the crankcase. Fit and
tighten the four screws to 9 Nm.
